Abstract Background: The increased use of diagnostic and therapeutic equipment and services increases the costs of the health system and insurance organizations. Evaluating the status of utilizing these services can provide a clear picture of the demand rate, responding process and methods of providing the relevant services. This study aimed to examine the status of using magnetic resonance imaging (MRI) services among the insured people by one of the insurance companies.Methods: This research was a descriptive and cross-sectional study. The studied statistical population included all insured persons covered by a private insurance company that had used the MRI services provided in hospitals and other diagnostic and treatment centers in 2018-2019. The data were analyzed using STATA and GIS statistical software.Results: In one contractual year, 22,738,215 medical expenses records have been filed in the entire country, out of which, 119,761 records (0.5% of all cases) were related to MRI services. The shares of the basic (main) insurer and supplemental insurance related to this service of the total MRI costs were estimated as 52,946,159,376 Rials (1,259,860.6077 USD) and 231,303,021,838 Rials (5,503,884.87252 USD), respectively. In the study, 102,024 people have used MRI at least once a year. The average cost of using MRI services at each time in the country was 2,373,470 Rials (56.47702 USD). The average number of referrals in the whole country was 0.07 times. The highest frequency of referrals was in Lorestan and Qom provinces, while Kerman and Sistan and Baluchestan provinces had the lowest frequency of referrals. The overall rate of utilization of MRI services in the country was estimated to be 6%.Conclusion: In general, the study results suggested a high rate of using MRI services in Iran, which can be due to the 100% coverage of costs by insurance companies and the increased access to health diagnostic and treatment services in the country.

The magnetic resonance imaging (MRI) machine cooling system has a vital role in the conduct of MRI examinations because a shutdown of the MRI cooling system in the absence of the manipulators can lead to grave consequences over time, like quench, which is the vaporization of helium liquid in the MRI tank, and it's the most expensive MRI failure. To limit the risks of this problem, several companies have tried to develop a monitoring system to track MRI cooling system failures but all solutions proposed are complicated and demand many connections with MRI. The proposed solution is simple, easy, and efficient requires only one joint with the helium compressor, and it has a humidity and temperature sensor to detect quench incident, it works using an advanced monitoring algorithm that evaluates the status of the cooling system and identifies breakdowns, in case of failure our system will send short message service (SMS) notifications and emails to the customer service team. The proposed solution shows the potential for starting the research to understand the relationship between the behavior of the MRI cooling system and the quench using machine learning algorithms.

BACKGROUND The craniovertebral junction is a complex articulation between occiput, atlas, axis and supporting ligaments enclosing the soft tissue structures of cervicomedullary junction which includes medulla, spinal cord and lower cranial nerves. The incidence of different types of CVJ anomalies varies with demographic environment & ill-defined genetic factors. CVJ anomalies are more frequently found in Indian subcontinent than anywhere else in the world. Even in India, these anomalies are more frequently documented from Bihar, Uttar Pradesh, Rajasthan and Gujarat. The reason for this geographical clustering is more speculative. The CVJ anomalies can be either due to bony or soft tissue anomalies. They are common in all age groups and almost equal in both sex groups. The anomalies can be due to congenital or acquired causes. There has been a renewed interest in the normal anatomy & pathological lesions of CVJ anomalies with dynamic xrays, computed tomography (CT) and magnetic resonance imaging (MRI). The clinical features are often delayed up to 2 nd or 3rd decade, since they are subtle and often missed. Various congenital anomalies and acquired disease processes can affect the craniovertebral junction. They often cause diagnostic dilemmas. Only few studies have been conducted in this regard. This study is an attempt to define importance of precise diagnosis for pre-treatment evaluation and systematic classification of CVJ abnormalities with MRI and multi-detector computed tomography (MDCT). METHODS We conducted this cross-sectional descriptive study with 55 patients, who had been referred to us for CT / MRI from Department of Neurology. 3 Tesla MRI (GE Healthcare) and 16 slice MDCT (Philips) were used in this study. RESULTS In our study, congenital anomalies were the most common type of CVJ abnormality followed by degenerative changes and trauma. MRI proved to be better at detecting soft tissue abnormalities and assessing spinal cord compression, although CT was very much accurate at demonstrating bony lesions with short scan times and ability to reconstruct in three orthogonal planes. CONCLUSIONS CT and MRI cannot be compared in imaging the craniovertebral junction and should be complementary to each other. KEYWORDS Craniovertebral Junction, MRI, MDCT

Psoriatic arthritis (PsA) presents with diverse features of musculoskeletal inflammation that affect both axial and peripheral joints as well as entheses, tenosynovium, and bursae. Magnetic resonance imaging (MRI) is the imaging modality that is uniquely capable of identifying pathology in all these structures. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Magnetic Resonance Imaging Working Group has increasingly explored diverse MRI methodologies for the purposes of quantifying inflammatory and structural abnormalities in clinical trials and research. The 2020 GRAPPA virtual workshop presented an opportunity to review progress in the field, summarize the status of MRI scoring systems developed for PsA, and review representative patient cases.

Ten children aged 1 week to 13 years with 12 vascular abnormalities were examined with magnetic resonance imaging (MRI) and other imaging modalities. MRI was the only single non-invasive modality that demonstrated all lesions and their internal structures. The vascular nature of 3 hemangiomas could not be established with MRI alone. No marked differences in MRI appearance was seen in 5 cases with vascular tumors compared with 5 cases with other vascular abnormalities. The status of the blood in the vascular lesions as flowing fast, slow, or not at all was successfully assessed in 9 of the 12 lesions.

Rectal cancer is one of the most common types of cancer in both men and women. In recent years, the importance of magnetic resonance imaging (MRI) has greatly increased in the multidisciplinary treatment of patients with rectal cancer. MRI has a particularly important role in the most accurate preoperative staging of these patients, both in terms of assessing the local invasion of the tumor and in terms of assessing the status of pelvic lymph nodes. Many patients with rectal cancer, especially those in the advanced stage of the disease, in the preoperative period undergo neoadjuvant radio chemotherapy. The evaluation of the clinical response of these patients to neoadjuvant therapy is of crucial importance both in terms of personalized treatment and in terms of their prognosis. In this regard, MRI has its clearly defined role at present in evaluating the efficacy of neoadjuvant therapy, as well as in postoperative follow-up.

Pelvic floor dysfunction is an important medical and social problem in the female population. The impact of pelvic floor disorders (PFD) is likely to grow as the prevalence of these disorders increases with an aging population. Pregnancy and delivery are considered major risk factors in the development of POP and stress urinary incontinence. Pelvic floor dysfunction may involve pelvic organ prolapse and/or pelvic floor relaxation. Organ prolapse can include any combination of the following: urethra (urethrocele), bladder (cystocele), or both (cystourethrocele), vaginal vault and cervix (vaginal vault prolapse), uterus (uterineprolapse), rectum (rectocele), sigmoid colon (sigmoidocele),and small bowel (enterocele).Given the paucity of understanding of PFD pathophysiology ,multicompartmental pathology, the high rate of recurrence and repeat surgery imaging plays a major role in its clinical management.The magnetic resonance imaging (MRI) allows noninvasive, radiation-free, rapid, high-resolution evaluation the multicompartment defects in one examination.Findings reported at MR imaging of the pelvic floor are valuable for selecting candidates for surgical treatment and for indicating the most appropriate surgical approach.

Introduction After stereotactic radiosurgery (srs) for brain metastases, patients are routinely monitored with magnetic resonance imaging (mri). The high rate of new brain metastases after srs treatment alone might not be as concerning with modern mri and target localization treatment. Intensive surveillance might induce anxiety, lowering the patient’s quality of life (qol). The present work is the feasibility component of a prospective study evaluating the role of surveillance mri on qol in patients with limited (1–3) brain metastases.Methods Patients with limited brain metastases treated with srs alone, an Eastern Cooperative Oncology Group performance status of 2 or less, and documented stability in treated lesions, with no new lesions seen on mri at weeks 6–10 after srs, were eligible. All were asked about their interest in participating in the control (mri and clinical surveillance) or the experimental arm (symptom-directed mri and clinical surveillance). If 33% or more agreed to participate in the experimental arm, it would be considered feasible to conduct the prospective study.Results From November 2014 to July 2015, 45% of patients (10 of 22) agreed to participate in the experimental arm. Subgroup analyses found that the decision to participate has no statistically significant association with time of presentation (p = 0.696), display of symptoms (p = 0.840), age (p = 0.135), or number of lesions (p = 0.171).Conclusions Results show that it is feasible to conduct the prospective cohort study. Because of the small sample size, we are limited in the conclusions able to be drawn in the subgroup analyses. However, the future study would allow for a better understanding of the attitudes of patients toward mri and its effect on qol.
